I mean even defining what is the "common good" is political and that is the point of the exercise. If art exists that is deemed bad for society then we tend to ban it. For example, there are people who define CSAM as art, but the cost to society is so great we don't allow even the possession of such material.

Why would I continue to waste time engaging in a respectful and interesting conversation with you when you're insistent on redefining my own comments and others' definitions solely so it fits within your own defined idea of politics? You're not engaging in good faith.
